So at preconception clinic you see a nurse at regular intervals (every 2-4 weeks) looking at your BG pattern, trying to eliminate hypos while reducing average and post prandial sugars. They will give you folic acid 5mg to take daily. You have monthly HBA1c to work towards getting it in range.
I was switched to a pump and asked to wait TTC conceive until I was well established on pump.
You have every chance of concieving naturally without IVF. Any questions let me know. I've found the preconception clinic great! I didn't go in my first pregnancy.
